INVENTOR. OWL/L jlZ Cbofwsw United States Patent C) 2,887,863 RINSE WRINGER CONSTRUCTION Orin N. Cooper, Garwin, Iowa Application May 6, 1955,Serial No. 506,515 6 Claims. (Cl. 68-22) wringer, all as more completelyset forth and described in my Patent No. 2,689,471, issued September 21,1954. The invention also comprises an improvement in the clothes rinsingmeansfor wringers as set forth in my copending application Serial No.259,741, filed on Decem her 4, 1951, 1956. g

When rinse water from an external source is applied to garments as theyenter the wringer rolls such additional and excess water must bedisposed of and kept from draining backinto the clothes washing tub.Some diversionis not entirely objectionable, but since the rinse wateris normally cold water this water would lower the tub water temperature.At the same time the tub water level will be raised above the normalhigh water level suited for the washing operation as recommended by thewashing machine manufacturer.

' Onefof the objects of this invention is to provide a now Patent No.2,748,586, dated June 5,

drain board for a wringer having a predetermined configuration andcontour to divert wringer rinse water toward and, into a rinse waterdrain area and away from flowage into the tub of the washing machine.

. Another object ofthe present invention is to provide a drain board foruse with a rinse wringer, arrangement and wherein said drain boardincludes a forward raised ridge or weir portion disposed to. terminatein vertical spaced relation above a horizontal plane coincident withthe-line'of Jtangency of the wringer rolls. With this provision'thegarments are held in suspended relation above the drain surface of thedrain board stretching between the raised ridge and the wringer rolls.

@Ahstillfurther object is. to position a rinse water dischargelarea as apar-tofthe drain board that is located.

toward the wringer rolls and well below-both the forward raised edgeofthefboard and the level of the line of tangencyofthe wringer rolls. 7j

:"As another object-of the invention the raised ridgeon the'drain'boardterminates in .a fairly sharp edge to provide a squeegeeorwash waterreleasing action to return a considerable amount of the wash water inthe clothes into th has the clothes are passing over the drain boardedge and on the "way to the wringer rolls. Thus less wash water icarriedover with the clothing during the wringer f'hnctidnandbetterrinsing results. 1 Q

other objects liavelto do with such factors as the use of a reverseslope 'on the drain board to divert water v with structural portions'the clothes path to rinse the toward the wringer rolls toward drainmeans and slope also prevents water from collecting or standing 1 uponany portion of the board drain surfaces; the, pro vision of a modifiedraised edge on the forward portion of the drain board to provide asqueegee edge arranged.. substantially at right angles to the liftingpull of the gar,-: ments going to the wringer; and also the provision ofundercut portions at the drain board raised edge and on, the wringerroll side thereof to further counteract possible overflow or return ofgarment water and rinse water back into the tub. g i Certain otherobjects relating to novel features ofthe present invention willhereinafter become apparent from} the following detailed descriptionhaving reference to the accompanying drawings illustrating theinventionand forming a part of this specification;

In the drawings: r Fig. l is a side elevation view of the upper part ofa washing machine having a wringer embodying the present invention, thewringer being shown in operative position and as it appears from theclothes receiving side thereof; Fig. 2 is a fragmentary vertical crosssectional view taken transversely through the wringer and wringer rollsand substantially as viewed along the plane of the line 22 in Fig. 1; eFig. 3 is a plan view of the drain board of the present invention as itappears when removed from-the wringer frame; and p Fig. 4 is afragmentary sectional view of a forward section of the drain boardconstruction of this invention but illustrating a modified design of araised forward; edge or weir. 1 Referring now to Fig. l, the washingmachine lha's' a tub 2 including a connected wringer post 3 to carry thebase fixture 4 of a wringer 5 that incorporates the drain board 6 of thepresent improved design. The wringer 5 carries upper andlower wringerrolls 7 and 8 respec'- tively suitably mounted in the wringer frame 9,with the operating handle 10 being provided to control the operas tionof the wringer in the conventional manner. The wringer also carriessuitable pressure release bars 11 and 12, the bar 11 being hollow as at13 to provide a, conduit along its length and also is provided with rowsof, small ports or openings 14 and 15 along the lower edge' of the'barto establish a clean water spray source above garments as they are fedinto the wringer rolls 7 and 8. i The drain board 6 comprises a verticalwall or apron 16 contiguously blending into end walls or aprons 17 and i18 with the apron 16 terminating with a raised forwardly disposed weiror ridge. 19 that leads between the up wardly positioned and upslopingend barriers 20 and I of the drain board 6. The balance ofthe drainboard' 6 includes a trough 22 defined by the upper surface of the" wallor bafile 23 and the inner surface of the connecting wall structurescomprising the weir 19 and barriersj20 f and 21. p j l The wringer sideor face 24 of the drain board 6 has suitable extensions 25 and 26adapted for securement of the wringer frame 9 to securely hold and mountthe drain board with its face24 flush against the adjacent wringer face27. p p The drain board 6 is also provided with a depending rearwardlysloping wall 28 including a heavier body section 29 formed between wall23 and wall 28 that is hollowed out at 30 to provide a rinse waterconduit. Rows of rinse water discharge ports 31 and 32 communicate withconduit 30 and these ports are positioned to direct a, rinse sprayagainst the underside of a garment such as when the latter is fedthrough thewringer rolls 7 land 8. j Rinse water may be supplied to thepressure release bar" 3 rinse water conduit 13 and to the drain boardrinse water conduit 30 through a flexible hose 34 connected with asuitable cold water supply and being joined with a nipple 35. secured tothe inlet leg 36' of a valve 37 that carries a valve wheel 38' to openor close the valve 37. Branch outlet nipples 39 and 40 each haveflexible hose sections 41 and 42 respectively which connect with inletnipples 43"and 44carried by the pressure release bar 11 and drainboardfi to communicate with conduits 13' and 30' respectively. Thusrinse water can be selectively turned on or off as required and thequantity of water may also be regulated for different conditions ofoperation or as may be desired by the operator.

A drain pan 45 is mounted in the wringer frame 9 and is fitted to thecavity of the wringer beneath the wringer rolls 7 and 8; The pan has adischarge nipple 45 to which a drain hose 47 is secured, the hose 47providing suitable means for the disposal of the wringer water to attainmm a pumpor' pump connection if that is feasible and desirable.

The forward top edge of the pan 45' is provided with an offset flange:or" rim 48 shaped to receive the depending'lip 49 that is part of thestructure of the wall 28 of the drain board 6. The rear top edge of thepan 45 also has an offsetflange or rim 50' to accommodate the dependinglip. 51 that is a part of the depending wall 52 of the rear or clothesdischarge board 53' that is secured to the rear face or side 54 ofthewringer frame 9. The rear discharge board presents the garment guidingtrough 55 as outlined by the contour and shape of the wall 56 and thedrop-01f apron 57.

Referring back to Fig. 2, it should be noted that the clothing. is fedto the wringer rolls 7 and 8 along a down slope. and this is emphasizedbythe general angularity of the garment 33 and also by the. slope of thedot and dash line 58; This arrangement, therefore, causes rinse Waterand extracted water to flow over the garment inthe generaldirection ofthe wringer rolls and about the garment to drain oifofthe wall 23 andout of the trough 22 over the surface of'wall 28 and into the drain pan45. Simultaneously, the sharp corner 59 on the top edge of the weir 19functions to extract a good portion of. wash water from the garment andwhich water drains back into the tube 2.

The trough wall 23 slopes down. as shown in Fig. 2, and from a levelabout coincidentwith the dot and dash line 60, which indicates ahorizontal'plane coincident with the tangency of the rolls, and to alevel where the rinse ports 31' and 32 are located. The object is tokeep the garments from riding on the trough. surface to promote freeuninterrupted flow of extracted and rinse water and to prevent mufilingor valving of the rinse water ports 31' and 32 which action would.interfere with the desirable and effici'ent garment penetration of therinse water streams or sprays.

I'n Fig. 4, a modified construction of drain board 6a incorporates adifferent form of weir structure 61 wherein the apron 16a terminateswith a horizontally disposed wash water extracting edge 62 under agenerally curved garment guiding ridge or crown 63. The trough side ofthe crown 63 is undercut at 64 to provide a water return well ordeflecting means that can be extended about the entire trough area ofthe drain board and up to the wringer frame face 27. One or more notches65 may be provided in the long. direction ofthe crown. as a furthermeans of retaining and rediverting some of the wash water from a garmentback into the tub.
